GH-608 wireless transmitter alarm probe is a wireless transmitter alarm probe produced by SUNSTAR. It uses imported PIR line infrared sensor and dedicated infrared IC for signal amplification, processing, and then through the dedicated data coding IC modulation, to produce the emission signal sent to the emission circuit.
The GH-608 is a wireless infrared detector that uses a pyroelectric sensor and SAW‑based 315 MHz transmission to detect motion over a 12 × 12 m area with a 110° detection angle. It features low static power consumption (≈50 µA) and a transmission current under 20 mA.
This manual describes the detector’s technical specifications, installation requirements, power‑up procedure, alarm delay configuration, and operating cycle (3 s transmission, 8 s interval). Contact information for Sunstar Automation and regional offices is also provided. This manual is written in Chinese.
| Operating Voltage | DC 9 V |

It requires about 2 minutes after initial power‑on before it enters normal detection mode.
Use a 30‑second delay and require signals from three detectors before the alarm system is activated.
The detector transmits at 315 MHz.
